Subject: net/sunrpc: Make rpc_auth_create_args a const
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=82b98ca566ca2af170eb0ab50cef09dd7335fa55;p=openwrt%2Fstaging%2Fblogic.git

net/sunrpc: Make rpc_auth_create_args a const

This turns rpc_auth_create_args into a const as it gets passed through the
auth stack.
